IMPROVEMENT IN WASH-BOARDS;

Specification forming part of Letters Patent No. 180,682, datedAugust 1, 1876 application filed July 15, 1876.

- durable, than wash-boards constructedin the usual way, and which may be made and sold at a'reasonable price.

The invention consists in an improved washboard formed of the grooved side bars, the center board, the rubber plate, the corrugated zinc plate, and the cross-strips, constructed and combined with each other as hereinafter fully described.

A are the side bars of the wash-board, in

' the inner sides of which, from their upper ends nearly to their lower ends, are formed wide grooves to receive the side edges of the center board B, the ends of the bars (J, and the side edgesof the zinc plateD. E is a rubber plate, which is passed alternately over and under the bars 0, so that a-rubber surface and a wooden surface may alternate with each other to form the rubbing-surface of this side of the board. This surface is more etfective than either a rubber surface or a wooden surface, as an entire rubber surface gives too much friction or causes the clothes to stick, and an. entire wooden surface allows the clothes to slide over ,it'too easily. The lower edge of the center board B,'the lower bar 0, and the lower edges of the zinc plate D, and of the rubber-plate E, rest "upon a cross-piece, F, the ends of which are secured in the lower ends of the grooves in the side bars A, and

upon the top of said parts B G D E rests across-piece, G, the ends of which are placed in the upper parts of the groovesin the side bars A, and which is pressed down, clamping all the parts firmly together by a strip of board, H, interposed between the cross-strip G and the crossstrip I, attached to the upper ends of the side bars A. The board H is made thin, so as to form a recess for soap between the strips G I, upon both sides ofthe wash-board.

Having'thus described my invention, Iclaim as new and desire to secure-by Letters Patent An improved wash-board, formed of the grooved side bars A, the center board" B, the

bars 0, the rubber plate E, thecorrugated zinc plate I), and the cross-strips F G H I,

constructed and combined with each other substantially as herein shown and described.
